I have a saito 40 inverted on a 4* 40 and am very pleased with the way it runs. I did cut the formers down and put tank at bottom of fus. I am doing a 4* 60 with a saito 100 inverted and plan to make a cowel simmilar to a curtis P40 Warhawk on this one. I do not have a way to send any photos, sorry.
